<p>PROBLEM TO BE SOLVED: To improve the control accuracy of a flow rate, to attain output reduction and miniaturization by lowering the pump-up level of a pump to be used for flow control while effectively using the supply pressure of tapped water, and to expand a flow control range concerning a flow controller for the sanitary cleaning device of the water supply directly tapped system. SOLUTION: This flow controller is provided with a flow control means 3 provided on a supply conduit 1 so as to control flow constant, waste water conduit 8 branched from this supply conduit 1 and main conduit 6 having a flow controllable pump 5 and at the branching part of the waste water conduit 8 and the main conduit 6, a pressure feedback branch valve 7 is provided for changing the aperture of a valve corresponding to the discharge pressure of the pump 5. Thus, the ability specification of the pump 5 is reduced and accuracy in flow control can be improved.</p> |
